METHOD OF MAKING A SEMICONDUCTOR DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18151990 titled 'METHOD OF MAKING A SEMICONDUCTOR DEVICE

Simplified Explanation

The abstract describes a method of fabricating a semiconductor device with specific features and structures. Here is a simplified explanation of the abstract:

  • The method involves creating a gate structure, a first edge structure, and a second edge structure on a semiconductor strip.
  • A first source/drain feature is formed between the gate structure and the first edge structure, and a second source/drain feature is formed between the gate structure and the second edge structure.
  • The distance between the gate structure and the first source/drain feature is different from the distance between the gate structure and the second source/drain feature.
  • The method also includes implanting a buried channel in the semiconductor strip, which is entirely below the top-most surface of the strip.
  • The maximum depth of the buried channel is less than the maximum depth of the first source/drain feature.
  • The dopant concentration of the buried channel is highest under the gate structure.

Potential applications of this technology:

  • Semiconductor devices such as transistors and integrated circuits.
  • Electronics industry for various electronic devices like smartphones, computers, and other consumer electronics.

Problems solved by this technology:

  • Provides a method for fabricating semiconductor devices with specific features and structures.
  • Allows for the creation of different distances between the gate structure and the source/drain features.
  • Enables the formation of a buried channel with a high dopant concentration under the gate structure.

Benefits of this technology:

  • Improved performance and functionality of semiconductor devices.
  • Enhanced control over the distances between the gate structure and the source/drain features.
  • Increased efficiency and reliability of the buried channel under the gate structure.


Original Abstract Submitted

A method of fabricating a semiconductor device includes forming a gate structure, a first edge structure and a second edge structure on a semiconductor strip. The method further includes forming a first source/drain feature between the gate structure and the first edge structure. The method further includes forming a second source/drain feature between the gate structure and the second edge structure, wherein a distance between the gate structure and the first source/drain feature is different from a distance between the gate structure and the second source/drain feature. The method further includes implanting a buried channel in the semiconductor strip, wherein the buried channel is entirely below a top-most surface of the semiconductor strip, a maximum depth of the buried channel is less than a maximum depth of the first source/drain feature, and a dopant concentration of the buried channel is highest under the gate structure.
